Paint Code Question

[JDMMA70]

So i have a two tone paint code is 21C, and according to PPG and other paint websites the top colour of my car the code is 8E3 (Dark Blue Pearl), well i bought a set of mirrors in the same colour and i notice the colour is off a bit, my car is a lighter more metallic blue. In direct sunlight you can hardly tell the colour difference or at night. Im just curious if 8E3 is indeed the correct colour for the top colour of my car. It would suck to get the nose panel, and targa resprayed and they dont even match.

Pic for refrence.

Thanks for taking the time to read this thread.

Could just be the difference in the conditions of the paint; I doubt all those paint companies could be off.
